Korekote GR

KOREKOTE GR is inready to use form dark grey coloured Alcohol base coating containing High Quality Refractory Material and Natural Graphite. It imparts low reactivity to the metal oxides & delivers excellent casting surface finish especially at High Pouring Temperatures.

It is suitable for brushing, dipping applications of Resin Bonded Complex core in the production of the castings like Cylinder Blocks, Cylinder Heads & the hydraulic components. It is recommended for Grey Cast Iron, S. G. Iron & Non Ferrous Alloys.

Physical Properties:

 

  • Colour - Dark Grey 
  • Specific Gravity - 1.0-1.05 gm/cc
  • Application Viscosity (By B4 Cup) - 13-16 seconds 
  • Solid content - 32-40%

Application Technique:

  • KOREKOTE GR is used for Grey Cast Iron, S. G. Iron & Non Ferrous Alloys castings especially Automobile castings. It can be applied on Cores & Moulds of all types of Resin Bonded Cores.
  • It is suitable for Dipping, Spraying, Brushing & Flooding or over-pouring type applications.
  • After coating applications, the cores are dried by ignition for few minutes which ensures uniform, homogenous & dense coating film.

Benefits:

  • Dipping Applications coupled with low preparation time & speedy deposit of coating on the cores offers high productivity.
  • As it is in ready to use form ensures thorough uniform mixing of all ingredients during manufacturing.
  • It offers wide uniform coverage which ensures good casting surface finish, free from veining & finning, sand fusion & penetration thus lowers the shot blasting, fettling & grinding costs.

Shelf life & Storage:

KOREKOTE GR has a shelf life of 6 months from the date of manufacture. The product should be stored in cool & dry place.

Lids of partly used Carboys should be replaced tightly.

Standard Packing:

KOREKOTE GR is available in 20 Kg Poly carboy/bucket.

Safety Precautions:

  • Remix the carboys contents thoroughly before transferring it to the dip tank.
  • Monitor the viscosity at periodic intervals especially after every two hours.
  • Use slow speed mixer to avoid air entrapment during continuous application.
  • To avoid formation of bacteria, clean the dip tank weekly.
